Description

Technical Field

[0001] The utility model relates to the technical field of adhesive materials, and particularly relates to a kitchen aluminum foil film. Background Art

[0002] During the daily use of the kitchen in life, a large amount of oil stains are inevitably generated. Although the range hood can remove most of the oil stains, it is inevitable that oil stains will accumulate at the air outlet of the range hood, the stove top, and the stove wall. Moreover, dirt and bacteria are likely to accumulate and breed in the corners and the gaps between the sink. To solve this problem, a wide-width PVC or PE single-sided tape is often attached to the wall next to the gas stove to isolate the oil stains and prevent the oil stains from damaging the wall. However, the traditional PVC or PE-based single-sided tape cannot withstand high temperatures. When the kitchen gas stove is working, the temperature around the stove is 60°C - 90°C, which will cause the tape to shrink and deform, affecting both the aesthetics and the anti-fouling effect. And when using it next to the kitchen stove, the issue of fire prevention needs to be considered. The traditional PVC or PE tape does not have a fire prevention function, which undoubtedly brings potential safety hazards. Content of the Utility Model

[0003] The purpose of the utility model is to provide a kitchen aluminum foil film aiming at the defects and deficiencies of the prior art, which has the advantages of anti-oil stain, water resistance, high temperature resistance, flame retardancy, and good adhesion.

[0008] A second flame retardant and water-resistant adhesive layer, which covers the second surface;

[0009] A release layer, which adheres to the side of the second flame retardant and water-resistant adhesive layer away from the aluminum foil layer.

[0010] The utility model is further arranged such that the material of the anti-oil stain layer is any one of TPX, PTFE, and PET.

[0025] Embodiment 1

[0026] This embodiment relates to a kitchen aluminum foil film. Referring to Figure 1 , it includes: an aluminum foil layer 100, a first flame-retardant and water-resistant adhesive layer 200, an anti-oil stain layer 300, a second flame-retardant and water-resistant adhesive layer 400, and a release layer 500. Among them, the aluminum foil layer 100 has a first surface and a second surface opposite to it; the first flame-retardant and water-resistant adhesive layer 200 covers the first surface of the aluminum foil layer 100; the anti-oil stain layer 300 adheres to the side of the first flame-retardant and water-resistant adhesive layer 200 away from the aluminum foil layer 100; the second flame-retardant and water-resistant adhesive layer 400 covers the second surface of the aluminum foil layer 100; the release layer 500 adheres to the side of the second flame-retardant and water-resistant adhesive layer 400 away from the aluminum foil layer 100. In this embodiment, an aluminum foil tape is selected to replace the traditional PVC or PE single-sided tape. Aluminum foil not only has the advantages of moisture-proof, good airtightness, light-shielding, fragrance preservation, and odorless, but also because of its elegant silver-white luster, various beautiful patterns and patterns of various colors can be processed. More importantly, its fire protection level is Class A, belonging to non-combustible materials. When encountering an open flame, it will only melt and will not burn, with high safety. A first flame-retardant and water-resistant adhesive layer 200 is covered on the first surface of the aluminum foil layer 100, and an anti-oil stain layer 300 adheres to the side of the first flame-retardant and water-resistant adhesive layer 200 away from the aluminum foil layer 100. Specifically, in this embodiment, the first surface is the high-gloss surface of the aluminum foil layer 100, and the second surface is the matte surface of the aluminum foil layer 100. An anti-oil stain layer 300 is provided on the high-gloss surface of the aluminum foil layer 100, which can not only resist oil stains but also ensure beauty by facing the high-gloss surface outward, and reduce the thickness of the aluminum foil to reduce costs, and can also provide excellent toughness and better adhesion to the aluminum foil layer 100. A second flame-retardant and water-resistant adhesive layer 400 is covered on the matte surface of the aluminum foil layer 100 for attaching the protection surface of various scenarios. The first flame-retardant and water-resistant adhesive layer 200 and the second flame-retardant and water-resistant adhesive layer 400 have excellent flame retardancy, further improving the flame retardant effect of the present utility model. In addition, the release layer 500 is used to reduce the influence of the second flame-retardant and water-resistant adhesive layer 400 deforming due to external forces, is not polluted, scratched, or bumped by foreign objects, and can be easily torn off during attachment, facilitating the attachment of the product.

[0027] Referring to Figure 1, the material of the anti-oil layer 300 is any one of TPX, PTFE, and PET. In this embodiment, the material of the anti-oil layer 300 is TPX. TPX has a high melting point and can be used at high temperatures; it also has an ultra-low surface tension and non-polar groups, which are extremely repulsive and incompatible with polar groups in substances such as oil, water, and gas. It is not easy to leave oil stains and is easy to clean, and has good oil resistance and self-lubrication ability. In some embodiments, the material of the anti-oil layer 300 can also be PTFE or PET. Further, the thickness of the anti-oil layer 300 is 10-100 μm. In this embodiment, the thickness of the anti-oil layer 300 is 25 μm. In other implementations, the thickness of the anti-oil layer 300 can also be: 10 μm, 15 μm, 20 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, 55 μm, 60 μm, 65 μm, 70 μm, 75 μm, 80 μm, 85 μm, 90 μm, 95 μm, 100 μm. As long as the thickness range of the anti-oil layer 300 is selected within 10-100 μm, no specific restrictions are made here. Preferably, the thickness of the anti-oil layer 300 is 25 μm.

[0028] Further, the thickness of the aluminum foil layer 100 is 10-50 μm. In this embodiment, the thickness of the aluminum foil layer 100 is 10 μm. In other implementations, the thickness of the aluminum foil layer 100 can also be 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm. As long as the thickness range of the aluminum foil layer 100 is selected within 10-50 μm, no specific restrictions are made here. Preferably, the thickness of the aluminum foil layer 100 is 10 μm.

[0029] Further, the release layer 500 is release paper or a release film, which plays a role in isolation, protection, and preventing the product surface from being contaminated. The release force of the release layer 500 is 5-50 gf, and its thickness is 50-100 μm. In this embodiment, the release layer 500 is a release film, its thickness is 50 μm, and its release force is 20 gf. The release film has the advantages of being easy to recycle, non-toxic, odorless, and having good mechanical properties. In some embodiments, the release force of the release layer 500 can also be 5 gf, 10 gf, 15 gf, 25 gf, 30 gf, 35 gf, 40 gf, 45 gf, 50 gf. The thickness of the release layer 500 can also be 55 μm, 60 μm, 65 μm, 70 μm, 75 μm, 80 μm, 85 μm, 90 μm, 95 μm, 100 μm. As long as the release force range of the release layer 500 is within 5-50 gf and the thickness range is within 50-100 μm, no specific restrictions are made here. Preferably, when the release layer 500 is release paper, its thickness is 80 μm; when the release layer 500 is a release film, its thickness is 50 μm.

[0030] In this embodiment, the first flame-retardant and water-resistant adhesive layer 200 and the second flame-retardant and water-resistant adhesive layer 400 are both water-resistant adhesives. Since the oil-resistant layer 300 and the aluminum foil layer 100 are inherently water-impermeable, the conventional aluminum foil tapes are not water-resistant and lose adhesion and come unstuck due to water penetration from the adhesive layer. In this embodiment, water-resistant adhesives are selected for the first flame-retardant and water-resistant adhesive layer 200 and the second flame-retardant and water-resistant adhesive layer 400, solving the problem of losing adhesion and coming unstuck caused by water penetration from the adhesive layer, and having not only good water resistance but also good flame-retardant performance.

[0031] Furthermore, the water-resistant adhesive is a water-dispersible water-resistant adhesive. In this embodiment, the water-dispersible water-resistant adhesive is commercially available Guanchuang 7533, which has characteristics such as non-combustibility, high temperature resistance, moisture resistance, and environmental protection and health. In addition, since the water-dispersible water-resistant adhesive is commercially available Guanchuang 7533 and itself has non-combustibility, it can achieve the function of flame retardancy. In this embodiment, a curable agent can also be added to cure into a film. In some embodiments, 0.12% of the curable agent can be selected to be added to make the curing effect better.

[0032] Furthermore, the thickness of the first flame-retardant and water-resistant adhesive layer 200 is 10 - 35 μm, and the thickness of the second flame-retardant and water-resistant adhesive layer 400 is 20 - 75 μm. In this embodiment, the thickness of the first flame-retardant and water-resistant adhesive layer 200 is 10 μm, and the thickness of the second flame-retardant and water-resistant adhesive layer 400 is 35 μm. In other embodiments, the thickness of the first flame-retardant and water-resistant adhesive layer 200 can also be 15 μm, 20 μm, 25 μm, 30 μm, 35 μm. The thickness of the second flame-retardant and water-resistant adhesive layer 400 can also be 20 μm, 25 μm, 30 μm, 40 μm, 45 μm, 50 μm, 55 μm, 60 μm, 65 μm, 70 μm, 75 μm. As long as the thickness range of the first flame-retardant and water-resistant adhesive layer 200 is 10 - 35 μm and the thickness range of the second flame-retardant and water-resistant adhesive layer 400 is 20 - 75 μm, there is no specific limitation here. Preferably, the thickness of the first flame-retardant and water-resistant adhesive layer 200 is 10 μm, and the thickness of the second flame-retardant and water-resistant adhesive layer 400 is 35 μm.

The thickness of the first flame-retardant water-resistant adhesive layer 200 is 10 μm, and the thickness of the second flame-retardant water-resistant adhesive layer 400 is 35 μm. In this embodiment, it can also be cured into a film by ultraviolet light curing. The aluminum foil layer 100 uses 10-μm aluminum foil. The release layer 500 is release paper with a thickness of 80 μm and a release force of 8-15 gf.
